In 1991, he took over as the Executive Director of USA Water Polo and helped bail out the nearly bankrupt sport's federation. His work laid the groundwork for the re-emergence of American water polo on the international scene. In his thirteen years as the Executive Director, Wigo increased membership from fewer than 8,000 members to more than 30,000 members. He also more than tripled the annual budget to over US$3.5 million and raised over US$1.5 million for the establishment of a water polo national training center in Los Alamitos, California.
In 2009, Wigo self-published the book The Golden Age of Swimming: A Picture History of the Sport & Pools That Changed America. The book chronicles the pastime's beginnings in ancient Rome, through the Victorian and into the 20th century. Its artwork comes from a collection of photographs, postcards, news clippings and other history sources, painstakingly assembled by Wigo. The Golden Age of Swimming also deals with the sport's darker past, such as racial discrimination when large public pools first became popular.
His oldest son, Wolf, is a three-time Olympic water polo player and currently the head water polo coach at the University of California at Santa Barbara. Daughter Lauren is the corporate yoga instructor for Allen & Company in New York City and his two younger sons, identical twins Drac and Janson, are NCAA All-American water polo players at Stanford University.
Wigo has also created the Swim Safety Device, a personal safety flotation device used by the open water swimming and triathlon markets.
